Hello Chris,
A mathematical (and practical) treatment of Multiple Tuning for vertical
antennas can be found in:
Radio Antenna Engineering
by Edmund Laport McGraw Hill NY 1952
pp. 38-43
This book is obviously out of print, but I could send you photocopies of the
relevant pages.

I would like to hear if anyone have tested the Multiple Tuned Vertical in some
form.
I have understood that the antenna transforms the feed impedance with a factor
equal to the square of the number of wires used. E.g.10 wires would raise the
feed impedance about 100 times.
I'm just rebuilding my LF-station and this antenna looks very interesting.
However, not much information has been found in my litterature. Links or
articles would be much appreciated.
